An object of the present invention is to provide aconnection between the adjacent ends of adjacent car bodies of an articulated can which will maintain these ends in their proper positions relative to each other and at the same time permit the bodies to swivel 'freely in all directions.

Another object of the invention is to provide the adjacent ends of-adjacent underframes of an articulated car with a joint which will permit said underframes to swivel freely in all directions and yet prevent relative bodily sidewise or vertical movement between the ends-of the underframes.

A further object of the invention is to provide a swivel connection between the adacent bodies of an articulated car, which comprises a projection formed on the under frame of one body and a recess formed in the adjacent underframe adapted to receive said projection so that the bodies can swivel freely in all directions and at the same time will be prevented from moving vertically or sidewise relative to each other.

These and other objects will be apparent from the following description.

Referring to the drawings in which like reference characters refer to like parts, Fig. l is a lan view of the adjacent end portions of two adjacent bodies of an articulated car embodying the invention, the superstructure being omitted; Fig. 2 is a longitudinal sectional view of the same taken on the line 2-2 of Fig. '1, and Fig. 3 is a plan view similar to Fig. 1 but showing a modification of the invention, the floor plate being omitted. p

Referring now in detail to the drawings, the reference character 1 indicates an articulated car unit which comprises a plurality of car bodies 2. In the accompanying drawings, the adjacent ends 3 of only two of such bodies have been illustrated, but it will be understood that an articulated car unit may comprise two or any other desired number of bodies 2. lit/hen the car unit comprises two bodies the adjacent ends 3 thereof are 1 carried by a single truck 4, as shown, in the drawings, and each of the outer ends of such bodies (not shown) is carried by a truck, thusa car unit of two bodies is carried by three trucks. more than two bodies, the outer ends of the bodies at opposite ends of the car are each carried by a. truck and the opposite end of When the car unit comprises! each of these bodies, and the adjacent end of an adjacent body is carried by a single truck, thus a car unit of three bodies will be carried by four trucks. The, truck 4: may be of any suitable form or construction and is preferably provided with a truck bolster Intermediate its ends this bolster is provided with a truck center plate 6 having a concave upper bearing surface 7 which around its upper portion terminates in an upwardly extending circular flan e 8. Each of the ends 3 of adjacent car bodies is provided with a member 9 which is suitabl secured to the underframe of the car ody and forms a portion thereof. Beyond the end of the car body this member is provided with an end wall 10 which extends on either side of thelongitudinal center line at such an angle that when the adjacent ends of two of the bodies are suitably mounted on "the truck, the walls 10 of the members 9 will not interfere with each other as the bodies swivel in passing around a curve. The outer end portion of this member 9 has a downwardly depending portion 11, the lower surface 12 of which is in the form of a portion of asphere and is adapted to engage a portion of the upper surface 7 of the center plate member 6 secured to the truck, which surfaces 12. and 7 conform in contour The flange 8 of the truck center plate is adapted to engage with a vertically disposed portion 13 of the ortion ll of the member 9 to prevent the accidental separation of the body and the truck. Above the surface 12 and preferably near the top o.

with each other.

of one of the members 9, there is provide a projection 14; which extends .outwardly from the end wall 10 and which at its outer end is in the form of a portion of a sphere. The other or adjacent member 9 has a re-v cess 15 formed therein and in which the outer end portion ofthe projection it is adapted to extend, such recess being so shapedas to permit a free swiveling movement between the bodies and yet prevent an verticall or sidewise movement, of the b0 ies relative to each other.

The surfaces 12 and 7 of the members 9 v and center bearing members 6 respectively, are concentric with the outer surface of the projection 14 so that when the adjacent ends of two car bodies are in their proper operative positions, as illustrated in the drawmgs, the projection 14 on the end of one of the 110 i and the surface engagement with each other, there being a bodies will extend into the recess 15 formed in the adjacent end of the adjacent body, 12 and 7 will be in sliding space 16 of varying width provided between the end walls 10 to permit free swiveling movement of one body relative to the other. It will here be noted that the connection between the car bodies and the truck is such that the projection 14, due to its engagement in'the recess 15, will prevent the underframe of one of the bodies from rising above the underirame of the adjacent body or any other'such bodily movement, and t at it w' 1 permit free swiveling movement of the odies relative to each other, and atthe same time maintain the ends of the bodies in such positions relative to each other that the longitudinal center lines of the bodies will pass through the center of the connection at all times re ardless of the angle one car assumes re ative to the other.

It will be further noted that the projection 14 when in the recess 15, rovides a means for transferring the bu ng shocks from one to the .other without having the walls 10 engage each other.

In Fig. 3 a modification of the invention has been illustrated in which the end of one body 'has secured thereto a separate member 17 having a recess 18 formed therein for the' reception of the projection 14 formed integral with a separate member 19 secured to the adjacent end of an ad acent body. In this modification it will be noted that these members ma be readily removed or replaced when desire without in any way interfering with the underframe or bodycenter bearing members. 1

It will be apparent to those skilled in the art to which this invention ap rtains that changes ma be made in the etails ofthe invention without departing from the spirit and scope of the appended claims.

Having thus described the invention what I claim as new and desire to secure by Letters Patent/is:-
